Due to bad weather today
I have been doing accounts and saw my mobile phone charges had increased for last two months. I examined the calls made on itemisation and found numerous numbers commencing 07953 93***** with different end numbers and all suggested diverted calls.
Good old I phone stores numbers and I was on phone for some of these times to known colleagues with different numbers
My account with T Mobile was checked after 20 mins on hold
and yes refunded straight away. Be warned check your bills
